I tried server.host option, looks like it only changed "Vite dev server running at" tips, server still listen on IPv6.

Hmm, according to Node docs server.listen supports both IPv6 and IPv4 by default.

Unless you want IPv4 only - which the fix allows you to do with host: '0.0.0.0'.

I believe you should point to this, which listen to IPv6 and IPv4 by default, but it's ipv6 only in default on Windows.

[yyx990803]

In most operating systems, listening to the unspecified IPv6 address (::) may cause the net.Server to also listen on the unspecified IPv4 address (0.0.0.0).

It seems it does listen to both in most cases.
